Question

A German scientist, George Ohm, discovered the relationship between current, voltage, and resistance. This became known as Ohm's law. According to Ohm’s law, if V is voltage, I is current, and R is resistance, their relationship is expressed by the equation A) I = V/R B) I = V × R C) I = V + R D) I = V – R

Answer 1

Answer:     A) $I=\frac{V}{R}$

Explanation:

According to Ohm's law, the current that flows through a conductor is directly proportional to the voltage and inversely proportional to the resistance.

As an easy way to understand it, voltage (V) can be seen as the force that moves the charges, the current (I) as the speed of the charges flow and the resistance (R) as the opposition to it.

So, the relationship is expressed by the equation:

                                         $I=\frac{V}{R}$

Answer 2

Choice A ... I = V/R ... is a correct form of Ohm's Law.
